Computar - VL7531S-MPZ - LensConnect 20 Megapixel 1" 75mm Lens F3.1 I2C Interface (C-Mount)

Product Overview

The Computar VL7531S-MPZ is an extreme telephoto LensConnect lens for 20-megapixel machine vision systems. With a 75mm focal length, it delivers the highest magnification in the series for resolving small details from long working distances on large 1" sensors.

Key Configuration

20MP optical resolution; 1" sensor support; 75mm telephoto focal length; S-series I2C control interface; motorized focus; motorized P-Iris; high-repeatability stepper motors; floating focus design; focus range from 0.45m to infinity.

Key Features

• 75mm focal length provides maximum telephoto reach for narrow-field, high-detail inspection.
• I2C interface enables direct board-level control from embedded vision hardware.
• Stepper-driven focus and iris support repeatable software presets for automated inspection workflows.
• P-Iris control allows precise aperture adjustment for contrast and depth-of-field optimization.
• Floating focus technology maintains 20MP clarity across the focus range from 0.45m to infinity.

Technical Context

The lens is designed for high-end OEM and embedded vision applications where optical adjustments must be controlled directly by a microcontroller, FPGA, or camera processing board. Its long focal length is well suited for inspecting small targets when the camera must be positioned far from the subject.

Installation Notes

The board-level I2C architecture supports compact integration without external USB control hardware. The 0.45m-to-infinity focus range makes the lens suitable for long working-distance inspection setups and automated systems with changing target positions.
